3. Problem description:

libxml2 is a library for manipulating XML files.

Multiple buffer overflow bugs have been found in libxml2 versions prior to 2.6.14. If an attacker can trick a user into passing a specially crafted FTP URL or FTP proxy URL to an application that uses the vulnerable functions of libxml2, it could be possible to execute arbitrary code. Additionally, if an attacker can return a specially crafted DNS request to libxml2, it could be possible to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0989 to this issue.

All users are advised to upgrade to this updated package, which contains backported patches and is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date
